5. Transmission of a radar screen's data requires transmission of data from 500000 pixels. Each pixel is binary: the probability of a 0 is 99%, and the probability of a 1 is 1%. There are 2 screens per second. (a) What is the information rate (hint: entropy) in bits per second? (b) Assuming that this is transmitted over a Gaussian channel with bandwidth 10kHz, what is the requisite SNR at the receiver?

5.
Transmission of a radar screen's data requires transmission of data from 500000 pixels.
Each pixel is binary: the probability of a 0 is 99%, and the probability of a 1 is 1%. There are 2
screens per second.
(a) What is the information rate (hint: entropy) in bits per second?
(b) Assuming that this is transmitted over a Gaussian channel with bandwidth 10kHz, what is
the requisite SNR at the receiver?
